These brackets at their upper portions are provided with ears e, which facilitate their attachment to the vertical face of work bench or table Suitable fastening devices iwould be applied to these ears, and also to the aforesaid bar 3. The upper portion of the device is formed into a heavy horizontal bar or beain '7,*as illustrated niost clearly in Fig. li, the rear face of which lies against the side of the table, as indicated. This bar 7 constitutes an anvil, against which'the teeth of a saw 3 may be set. For this urpo-se the forward Vface of the bar or anvi ,7 1s beveled, so as 'to present an inclined cheek 9.

'to b -l .set will be 'described more fully herein after. in order to hold the saw-in position, the upper part of the device isforined into a vise i0, having a inain jaw 1l and a clamping-jaw i2. The outer jaw 12 presents an elongatedbody 13, formed with a substantially vertical clarnpingdace 14, and neari'ts extremities' this body is formed with integral arms l5, which preferably curve downf wardly and outwardly, as shown, their lower lextrernities being rotatably mounted upon a shaft i6.' This shaft 16 is supported at its extremities in vertical arms 17, which pr0- ject upwardly and constitptejthe outer portions of the brackets 2.. ln order to enable the .1.2 to be adjusted toward its'opposing o jaw` the upper extremities of the arin 17 are provided. with set-screws -18, the extremities whereof project on the inner ed es of the arms and abut against the outer ace of the in foi-1n' to the body 13 of the opposite jaw.

Near its extremities thebody i9l isfformed with longitudinally-projecting gudgeons 2:0,

which are of half-round forni, as indicated in' Fig. 3. These gudgeons are received in half-round recesses 21, formed. inthe outer face of the anvil 7 at its extremities. On the rear face of the body 19 of the jaw projecting ears 22 are provided which are disposed a slight distance above the upper face 23 of the anvil, as indicated in Fig. e. Throu 'h these ears 22 adjusting-screws 24, pass, an the ezttrernities of these adjusting-screws rest upon the face 23, indicated. ith this arran enient the l1 is held in position on t ie anvil, and it evidently may Ybe adjusted by means of the screws 2:4, so as to alter the positien of its clampin '-face 25. As shown clearly in Fig. Ll, the ainping-face 25 of the main 1l is substantially flush with the lforward face of the anvil, this arrangement being` adopted for a purpose which will appear more fully hereirmfter.v The main jaw li presents a longitudinallyLdisposed lower edge 9, which is beveled, as shown most clearly in Fig. 4. The intersection of this edge with the outer face 25 ol.' the jaw ylies substantially upongthe axes of the gudgeons 20. As stated above, the. gudgeons 20 are ICO - instrument applied thereto.

Y' blade.

of half-round form, and their'ilat faces constitute continuations of the outer face 25 of the main jaw 11. From this arrangement the jaw 11 may be readily set into position by moving the same laterally in a horizontal position and so that the gudgeons 20 will pass into their recesses.

Upon the shaft 16 there is'loosely mounted so as to slide and rotate a punch 26, said punch comprising an arm 27 and a body 28. vAsindicated in Fig. 1, the forward extremity of the punch-body 28 has the form of a segment of a circle presenting an acute or Vf pointed edge 29. v

In operating the device to sharpen the teeth of a saw with an instrument suchl as a lile the saw would be held in position asindicated in Fig. 1. The teeth of the saw would then project' just above the clampingj aw in a convenient position to have the sharpening As will be readily understood from the description of the vise, the saw-blade would be held firmly in position. by screwing up the adjustingscrews 18, sai screws operating to clamp the saw-blade against the m 'n jaw 11.' When using the device to set the teeth of a saw, the saw-blade would be turned'into an inverted position, such as that indicated in Fig. 2, at whichy time theteeth would project below the lower edge of the clamping-jaw 12 and lie substantially. in front 045- the inclined cheek 9, described above. Wi [i the saw held in this position the punch 2 would be applied,` as indicated in Fig. 2. Its point would be applied to the altern.- te teeth,V and when so applied the butt 80 oi' the punch would be struck by a hammer, so as to force these alternate teeth' against the beveled cheek a this way the teeth would be offset or at troni the plane of the body ol' the 'ine free sliding connection of the punch with the shaft 16 enables the punch to be slid along from tooth `to tooth until the setting operation is iinished. After all of these alternate teeth have been set in the manner described the saw-blade would then be reversed, so as to enable the intermediate teeth to be set in a similli'lmanner. By adjusting the screws 24 the angular position of the main jaw 11 can be changed as described.

In .this way the position 'in which the sawblade is held may be varied. Conse uently the amount of set of the teeth can econtrolled,`the same being more or less, depending upon the angular position of the jaW 11,

as will be readily understood. Attentionis bars, the upper bar being enlarged and form-i ing an anvil, the brackets being provided with means whereby they may be securedI to a bench, a mainjaw pivotelly and adjustably mounted on the anvil, a movable jaw,.pro vided at each end with a downwardly-curved arm, said jaw being of a -width greater than that of the main jaw with its upper edge flush with the upper edge of said main jaw and its lower edge extending down below the upper face oi the anvil, a-rod secured in the outer members of the brackets with its ends projectting through the same and upon which ends the arms of the movable jaw are pivoted, a punch having an arm projecting at an angle therefrom, said arm beingloosely mounted upon the said rod, and 'a screw working in the upper end of each of the outer members of the bracketsand,engaging the movable jaw.

In testimony whereof I havevsign-ed my name to this speciiication in the presence of two subscribing witnesses.
